Re: [U-Boot-Users] mkimage on 64bit

Dear David,

in message edmpdq$u74$1@sea.gmane.org you wrote:

Unless something like enclosed patch is applied, tools/mkimage cannot show image headers when built on 64bit platform, due to size problem of 'unsigned long'.

First, I think your patch is inconsequent:

uint32_t pos;

• unsigned long *len_ptr = (unsigned long *) (
  

• uint32_t *len_ptr = (uint32_t *) (
  		(unsigned long)hdr + sizeof(image_header_t)
  	);
  

If you change the "unsigned long" in the first line, then you probably want to change the "(unsigned long)hdr", too.

From you patch it seems that on your platform a pointer to "unsigned

long" is different from a pointer to uint32_t? Is this really the case?

I cannot confirm your problem on a 64 bit AMD Opteron system:

-> file ./mkimage ./mkimage: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.4.0, dynamically linked (uses shared libs), stripped -> ./mkimage -l /tftpboot/ebony/uImage Image Name: Linux-2.6.14-rc1-gd8ac1063 Created: Wed Sep 14 14:57:10 2005 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 947802 Bytes = 925.59 kB = 0.90 MB Load Address: 0x00000000 Entry Point: 0x00000000

So for me this works fine.

Can you please explain which sort of system you are working on, and what's going on there?

Best regards,

Wolfgang Denk
